CARDFING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 469,381, dated February23, 18925 Application filed $eptember4,1891, Serial 110,404,762. some Toall whom itv may concern:

Be it known that I, EMIL ()swALD ZEUNERT, a subject of .the King ofSaxony, residing at L'eisnig, in the Kingdom of Saxony, Germany,haveinventednewandusefullmprovementsin Oarding-Machines with Olearers,of which the following is afull, clear, and exact description.

The object of this invention is to provide an automatic contrivance bymeans of which the refuse or waste material from cardingmachines isremoved from the working parts of the machines, as required, withoutrisk of injury to the workers. According to my invention such refuse orwaste material is collected into boxes or receptacles of suitable formand dimensions, from which it may be ultimately taken during the leisurehours of the operators or at the end of the day, when the machines haveceased to work.

In carrying out my invention I adopt the arrangements hereinafterdescribed,and illus trated by the accompanying drawings, in which--Figure 1 is a front View of a part of a carding-machine with clearers,having my improvements adapted thereto. Fig. 2 is a back view thereof.Fig. 3 is an enlarged side elevation of one of the clearing boxes orreceptacles with my improved automatic contrivance for removing therefuse or waste material from the carding-cylinders. Fig. 4 is anenlarged front elevation, and Fig. 5 an enlarged bottom plan thereof.

Similar letters of reference indicate corresponding parts in all thefigures.

The box or receptacle a, in which the refuse or waste material iscollected, contains the spindle or axis 19, parallel to the axis of theclearing-roller XV. To the spindle or axis 1) is affixed the flat bladeor knife m, the upper edge of which is pressed against theclearing-roller W by the action of arm d, operated by projecting arm 6,and is caused to fall away from the said roller by the action of theweight g after being released from catch or nose at by levers h and q.The said lever h is mounted on end of revolvingbar or spindle i, towhich motion is imparted by a worm-wheel r, gearing with a screw-shaftZ, operated by a traveling band or cord 25 over the rollers 7c Theroller 7c is mounted on the axis or spindle of roller A, Fig. 1, throughwhich it has motion imparted to it, and thence through the travelingband or cord 25 to the roller Upon the axis of roller A is theradially-projecting arm 6, which comes in contact during its rotationwith the end of arm cl, fixed upon the spindle b of knife or blade m,causing the latter to be forced up against the roller \V. The knife 'mis maintained in that position by the nosen on angle-lever g pressingagainst it. The angle-lever q is held firmly in position, so that thenose n presses against knife m by means of spring f but when therotation of the apparatus brings the end of lever h against the arm oflever q the latter is forced down, as shown by dotted lines in Fig. 3,whereby the knife on is released and caused by counter-weight g to fallback from clearing-cylinderW against roller 1) in box a. The waste orrefuse material collec ed from roller W is thus thrown into the box orreceptacle and the cylinders are kept clear of such material, the shields,fixed on top of box a,guarding the cylinder and preventing thematerial fiying outside of said box or receptacle.

In the back view, Fig.2,is shown the mechanism by which the movements ofspindle b are conveyed to the corresponding spindle or axis of the knifem in the next adjacent clearing box or receptacle. This mechanismcomprises connecting rod. or switch at, supported between crank-arms 0o, and causes the knives m m to move simultaneously in the same manner.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- In a carding-machinewithclearing-rollers, a box or receptacle a, adapted to collect the refuseor waste material, a spindle b, pivotally secured within said box andparallelwith the axle of the clearing-roller, said spindle beingprovided with an arm d, a rotating arm e, adapted to control the motionof arm d, a knife or blade on, firmly secured to said spindle andadapted to be alternately carried to and from the said roller, a spindle1', arranged at right angles to spindle b, an angle-lever h, secured tothe forward end of spindle 2', a counterweight g, secured to spindle b,the said angle-lever h, rotating arm 6, and counterweight 9 beingadapted to control the toand-fro motion of the knife m, a worm-wheel r,secured to the outer end of spindle i, screw- In witness whereof I havehereunto signed shaft Z, adapted to gear with said Worm-Wheel, my namein the presence of two subscribing and a band or cord 25, adapted totransmit the Witnesses.

motion of the machine to the said screw-shaft, EMIL OSWALD ZEUNERT. allsaid parts being arranged and adapted to witnesses: I operatesubstantially as described, and for the R. E. J AHN,

purposes set forth. W. P. BOYD.
